5.Language Use

Original: According to the lecture, there are two reasons why some plants avoid light. The first reason is that some plants may depend on some objects to support themselves to live. A good example of this is the winged vine plant. Some wings may live in shadow until they reach the trees or buildings to support their life. Another reason is that some plants may avoid exposure to the sun's ray. To illustrate, if the sunlight is too intense, the plants will lose so much water, thus get dried out. Therefore, to avoid the intense sunlight, the plant will change their position of leaves. A good example of this is the bean plant, which turns their leaves away when exposed to the strong sunlight.

(The word "winged" was replaced with "vine" for accuracy and clarity.)

Revised (140 words): According to the lecture, there are two primary reasons why certain plants avoid light. The first reason is that some plants rely on external objects for support in order to grow properly. A prime example of this is the vine plant, which grows in shadows until it reaches a tree or building for support. The second reason is that certain plants need to minimize exposure to sunlight in order to conserve moisture. For instance, when sunlight becomes too intense, plants risk losing excessive amounts of water and consequently drying out. To counteract this issue, these plants adjust the position of their leaves to reduce exposure. A notable example of this adaptation can be observed in bean plants, which rotate their leaves away from direct sunlight when exposed to harsh conditions. By employing these strategies, both vine and bean plants effectively avoid light for their respective reasons.

5.语言使用

Original Answer: The lecture explains two reasons that some plants avoid light. The first reason is they need other objects to grow on for support. So they are attracted to a dark shadow. For instance, vines grow in dark shadows until they reach a tree or a building. After they reach there, they are grown to climb up and grow on that object. The other reason is that the plants need to conserve moisture. When they are exposed to intense sunlight, they will lose water. So they need to change their position of leaves for retaining moisture. Take a sort of bean plant for instance. When they sense the strong sunlight, they are going to change their leaf to the side way. In this case, they can avoid being dried out. These are two strategies plants use to avoid light.

Corrected Answer: The lecture discusses two reasons why some plants avoid light. The first reason is their need for other objects to grow on for support. As a result, they are attracted to dark shadows. For example, vines grow in dark shadows until they find a tree or a building. Once they reach it, they climb up and grow on that object. The second reason is the plants' need to conserve moisture. When exposed to intense sunlight, they lose water and must adjust the position of their leaves to retain moisture. Consider the bean plant as an example; when it senses strong sunlight, it changes its leaves' orientation sideways so that only the thin edge faces the sun, preventing them from drying out. (原文中的“they are grown”改为“they climb”，因为这样更自然。另外，将“a sort of bean plant”改为“the bean plant”，以保持一致性。) These are two strategies plants use to avoid light.

Original Answer: Many plants were willing to be seek the sunlight to get enough shine, and there are many plants that will avoid the light. In the lecture, the professor used two reasons to illustrate it. The first one is that some plants need some objects like trees to support themselves. Even though the lights under the trees are dark, these plants will grow along the tree. This is one example. It is a kind of plant that is growing in a shadow under the trees or under the building. The second reason is that the dark environment helps the plants to conserve their moisture. When it is exposed to the sunlight, it is dangerous for some plants because they will lose some moisture. But under the dark environment, it is more safe. Take the bean plant as an example. Under the middle of the day, it will still live in order to protect itself.

(将“were willing to be”改为“seek”，使句子更自然。)

Revised Answer (140 words): In the lecture, we learn that some plants seek sunlight while others avoid it for various reasons. The professor provided two examples to illustrate this phenomenon. Firstly, certain plants require objects like trees for support and grow towards darker areas where these objects cast shadows. For instance, vines grow in shadows until they reach a tree or building, then climb up for support.

Secondly, some plants avoid light to conserve moisture as intense sunlight can cause them to lose water and dry out. For example, a species of bean plant changes its leaves' position during intense sunlight in order to minimize exposure and retain moisture.

In conclusion, while many plants seek sunlight for growth, others like vines and bean plants avoid light for reasons such as finding support or conserving moisture.

Original Answer: The biology lecture discusses the reason why some plants avoid the sun. First, some plants need to find other objects like trees to cling to, attracted by the shadow of tall objects. These plants grow along the shadow of tall objects. For instance, why plants grow up in shadows until they reach tall objects like trees or buildings, so that they can grow up less objects? Second, certain plants conserve their moisture by avoiding the sun, because intense sunlight makes these plants lose water. During the day when sunlight is strong, some plants change their direction of leaves, decreasing the exposure to sun. In the example of bean present, when sunlight is too strong in the middle of the day, bean plants will turn leaves into sideways, avoiding drying out. These three examples illustrate the reason why.

Corrected Answer: The biology lecture discusses the reasons why some plants avoid light. First, some plants need to find other objects(原文中的表达不够清晰，改为更自然的表达方式) like trees to cling to, attracted by the shadow of tall objects. These plants grow along the shadows cast by tall objects. For instance, vines grow in shadows until they reach tall objects like trees or buildings, so that they can be supported by them(修改了原文中的疑问句，使其更符合语境). Second, certain plants conserve their moisture by avoiding light, because intense sunlight makes these plants lose water.

The speaker's delivery is mostly clear and fluid, but there are some occasional pauses that disrupt the flow of speech. To improve, the speaker should practice speaking more consistently and work on reducing unnecessary pauses. Additionally, the speaker should focus on accurate pronunciation to avoid any spelling errors that may arise from mispronunciation.

4.Topic Development The response is coherent and well-organized, with clear connections between ideas and sufficient support or examples. However, there is room for improvement in terms of providing more specific details about the vine and bean plant examples. The speaker could also work on refining their language use to make their explanations more concise and precise. Overall, practicing and refining these aspects will lead to a stronger topic development in future responses.

5.Language Use

Original: The professor goes into a tonlot ("ton" is informal, use "lot" for a more formal tone) of detail about the plants which are avoiding the sunlight. Many plants want to get sunlight because they want to grow taller, while on the other hand many plants don't want to meetreceive (use "receive" instead of "meet" for clarity) the sunlight during the day. For one example is the vines. Vines grow in dark shadows which are covered by tall trees. They grow on tall trees and grow taller. Secondly, the professor said many plants don't want to get sunlight because sunlight can lead to the evaporation in the plant's leaves. Plants want to retain their moisture, such as the bean plant. When they think the sunlight is too strong, they put their leaves sideways, therefore it can retain their moisture.

Revised (140 words): The professor provides a lot of detail about plants that avoid sunlight. Some plants seek sunlight to grow taller, while others prefer not to receive excessive sunlight during the day. One example is vines, which grow in dark shadows cast by tall trees. These vines rely on trees for support as they grow upward. Another example mentioned by the professor is that many plants avoid direct sunlight to prevent excessive evaporation from their leaves and conserve moisture. The bean plant serves as an illustration of this strategy; when exposed to intense sunlight, it adjusts its leaves' position sideways, reducing exposure and retaining moisture more effectively. By understanding these examples, we can appreciate the diverse ways in which plants adapt to their environment and optimize their growth.

Original Answer: Should professor use the examples of the wine vine and the bean plant discussed two reasons that some counsel white lies? One is the wine vine tree, it can make the shadow and conserve the moisture, and it's too awkward. And the bean plant, it is dangerous to dry and it can maintain the moisture.

(原文中的 "wine" 应改为 "vine"，因为这里讨论的是藤蔓植物。)

Corrected Answer: The professor discussed two reasons why some plants avoid light using the examples of the vine and the bean plant. One reason is that plants like vines grow in shadows to find tall objects for support, eventually climbing up these objects. Another reason is that some plants, such as bean plants, change the position of their leaves to reduce exposure to intense sunlight and conserve moisture.

Revised 140-word Answer: The professor explained two reasons why certain plants avoid light by using examples of vines and bean plants. Firstly, some plants like vines actively grow in shadows to locate tall objects like trees or buildings for support. Once they reach these objects, they climb or grow upwards along them. This behavior allows them to find a stable structure to grow on while avoiding direct sunlight. Secondly, other plants such as bean plants have developed mechanisms to conserve moisture by reducing their exposure to intense sunlight. They achieve this by changing the position of their leaves during periods of strong sunlight, turning them sideways so that only the thin edges are exposed to the sun's rays. This adaptation helps them retain moisture and prevents them from drying out due to excessive sunlight exposure.

Original Answer: Well, the first reason is that some trees need to grow on and they are attracted by dark shadow. So by the dark shadow, they could grow to the tall places. For example, a tree, a wine tree, they would climb to the places where there are dark shadows. And the second reason is to conserve moisture and water. For example, bean plants, when the sun is too strong, bean plants would change the direction of their leaves. So only one side of their leaves would be exposed to the sun. And in this way, the bean plants could avoid drying out by conserving moisture. And these are the two reasons that some plants avoid light. And yeah.

Corrected Answer: Well, the first reason is that some trees plants need to grow on and they are attracted by dark shadow shadows. So by following the shadows, they could grow to reach tall objects. For example, a tree vine, would climb to places where there are dark shadows. The second reason is to conserve moisture and water. For example, bean plants, when the sun is too strong, would change the direction of their leaves so that only one side of their leaves would be exposed to the sun. In this way, bean plants can avoid drying out by conserving moisture. These are two reasons why some plants avoid light.

(原文中的“trees”应改为“plants”，因为这里讨论的是植物，而不仅仅是树。另外，“dark shadow”应改为“shadows”，因为“shadow”已经表示了阴影的意思，不需要加“dark”。在描述藤蔓的例子时，应将“tree”改为“vine”，以保持一致性。)

Revised Answer (140 words): The first reason some plants avoid light is that they need to grow on other objects for support and are attracted to shadows. By following these shadows, they can reach tall objects like trees or buildings. For instance, vines grow along the ground in shadows until they find a suitable object to climb, such as a tree or building. The second reason is to conserve moisture and water. Bean plants, for example, change the position of their leaves when the sunlight is too intense. They turn their leaves sideways so that only the thin edge is exposed to the sun, reducing water loss. In this way, bean plants can avoid drying out and maintain their moisture levels. These two examples demonstrate why some plants have developed strategies to avoid light in certain situations.

5.Language Use

Original: According to the lecture, there are mainly two reasons for why some plants avoid sunlight. First is, some plants prefer to seek a tree to climb to. And the vine is a great example that they search for a dark shadow, which indicates a tall building or tall objects, and they will grow toward the direction of the dark shadow. And then when they finally reach the tree or a high object, they will climb into the high object. And second is for the protection of their moisture, because the intense sunlight of the sun may dehydrate the plant. And for example, the bean plant, they will change their direction. If they have some intense sunlight, they will change towards sideways. So only part of the body will be rejected by the sunlight.

Corrected: According to the lecture, there are mainly primarily two reasons (more formal vocabulary) for why some plants avoid sunlight. First, some plants prefer to seek a tree to climb. The vine is a great example; they search for a dark shadow, which indicates a tall building or tall objects, and they grow towards (corrected preposition) the direction of the dark shadow. When they finally reach the tree or a high object, they climb into onto (corrected preposition) the high object. The second reason is for the protection of their moisture, because the intense sunlight of the sun (redundant) may dehydrate the plant. For example, the bean plant will change its direction. If it receives intense sunlight, it will change towards sideways to a sideways position (clearer phrasing). So only part of the body will be rejected shielded (more accurate verb) by the sunlight.

For example, the bean plant will change its direction when exposed to intense sunlight. It will adjust its leaves to a sideways position, so only part of its body is shielded by the sunlight. This adaptation helps plants like vines and bean plants survive in their respective environments while avoiding excessive exposure to sunlight.

Original Answer: The professor gave two reasons of some plants will grow avoid light. The professor mentioned two reasons why some plants grow to avoid light. (原句中的表达不够自然，修改为更自然的表达方式。) The first reason is that they need some objects to clean and grow. The first reason is that they need objects to cling to and grow on. (修改了不准确的词汇和语法错误。) The professor gave the example of vines. These vines need to grow up by cleaning some objects like tall trees and buildings. So they have to find shadows created by the tall trees and buildings cast on the ground. Then they reach up and enjoy the sunlight. For the second reason, some plants avoid light because they need to reserve the moisture in their body. The professor gave the example of the bean plants. They usually sideways their leaves in the middle of the day. So they can let the thin edge be exposed by the sunlight and reduce the exposure during the middle of the day.

Revised Answer (140 words):

The professor mentioned two reasons why some plants grow to avoid light. The first reason is that they need objects to cling to and grow on for support, such as tall trees or buildings. The professor provided an example of vines, which seek out shadows created by these tall structures, eventually reaching them and growing upward along them, benefiting from their support. The second reason is that some plants avoid light in order to conserve moisture within their bodies. The professor used bean plants as an example, explaining that they reposition their leaves during intense sunlight in the middle of the day. By turning their leaves sideways, they expose only the thin edges to the sun, reducing overall exposure and helping to retain moisture.

3.Delivery The speaker's delivery could use some improvement. The speech is not very clear and fluid, with occasional pauses and some pronunciation issues. To improve, the speaker should practice speaking more clearly and at a consistent pace, focusing on proper pronunciation of words. Additionally, working on reducing pauses will help the speech flow more smoothly.

4.Topic Development The topic development in the response is quite good. The speaker provides a coherent and well-organized response, with clear connections between ideas and sufficient support or examples. However, there are some minor issues with word choice and repetition that could be improved. To enhance topic development further, the speaker should work on using more varied vocabulary and avoiding repetition of words or phrases.

5.Language Use

In the lesson sections, the professor gives the examples of the 1 vine and the B bean plant to discuss the two reasons that some plants over delight avoid light. The first reason is that some plants, they need to grow up because they rely on the tall trees. For example, like the wind trees vines. So they need to rely on the tall trees for growing up. So that's why they over delight avoid light. (Replace "1" with "vine" and "B" with "bean" for clarity. Replace "over delight" with "avoid light" for accurate vocabulary usage.) The second reason is some plants, they over delight avoid light because they want to keep the moisture. So still the example is the B bean plant. This kind of the plant, they turn their leaves down side to the sunlight. Because the sunlight will vaporize the water in the leaves. So that if the leaves are face to the sunlight, they will be dried easily. However, if they are not face to the sunlight, so they will keep the moisture inside the leaves. That's the two reasons for some plants over delight avoid light. (Replace "B" with "bean" for clarity and replace "over delight" with "avoid light" for accurate vocabulary usage.)

Revised Answer (140 words):

In the lecture, the professor discusses two reasons why some plants avoid light using examples of vines and bean plants. The first reason is that certain plants need support from taller objects like trees to grow upwards. Vines are an example of this; they grow in shadows until they reach a tree or building, then climb or grow up that object. This is why they avoid light. The second reason is that some plants avoid light to conserve moisture. For instance, bean plants turn their leaves sideways when sunlight is too strong, so the sun only hits the thin edges of the leaves. This helps the plant retain moisture and prevents it from drying out. In summary, some plants avoid light to find support for growth or to conserve moisture, as demonstrated by the examples of vines and bean plants.

5.语言使用

Original Answer: The professor uses two examples to discuss the reasons that plants avoid light. The first reason is that some plants want to find the tall objects to grow on. So that when they are attracted to the shadow, they will reach the tall objects easily. For example, the vines can grow in shadow and they will reach the tree and finally grow up the tree. The second reason is that they want to conserve moisture. Since the plants always grow towards the sun, during the day when the sun is too intense, they will dry the plant too quickly. So in order to avoid being dried too quickly, the plants can change the position to avoid sunlight. For example, this bean plant, when it senses the intense sunlight, it will change direction and make the thin edge face the sun to avoid being dried.

Corrected Answer: The professor uses two examples to discuss why plants avoid light. The first reason is that some plants need (需要) to find tall objects to grow on, (，) so when they are attracted to the shadows(阴影), they can reach these tall objects easily. For example, vines grow in shadows until they reach a tree or building, (，) and then climb or grow up that object. The second reason is that some plants want to conserve moisture. Since plants usually grow towards the sun, during the day when the sunlight is too intense, they may dry out too quickly. To avoid this, plants can change their position to minimize sunlight exposure. For instance, a species of bean plant turns its leaves sideways when it senses intense sunlight, making the thin edge face the sun to prevent drying out.

Revised Answer (140 words): The professor discusses why plants avoid light using two examples. Firstly, some plants need tall objects for support and grow towards shadows to find them. Vines, for example, grow in shadows until they reach a tree or building and then climb or grow up that object. Secondly, some plants aim to conserve moisture by minimizing sunlight exposure. Plants usually grow towards the sun, but intense sunlight can cause them to dry out quickly. To prevent this, they change their position. A species of bean plant turns its leaves sideways when sensing intense sunlight, making the thin edge face the sun to avoid drying out. These examples demonstrate that plants may avoid light for structural support or moisture conservation purposes.
